  摘要：

  肿瘤相关的跨膜碳酸酐酶（CA，EC 4.2.1.1）同工酶IX（CA IX）在低氧性肿瘤中过表达，并且似乎参与了肿瘤微环境的酸化，该过程与癌症的进展和不良的预后相关。可以通过用强效的磺酰胺/氨基磺酸CA抑制剂抑制酶来减少酸化作用。已经制备了一系列结合有硫脲基-磺酰苯胺基部分的芳族磺酰胺，并研究了其与人同工酶hCA IX的催化结构域的相互作用。合成中的关键中间体是通过使磺胺，高磺酰胺或4-氨基乙基苯磺酰胺与4-乙酰氨基-苯磺酰氯反应，然后脱乙酰基并与硫光气反应而获得的。使获得的异硫氰酸根合磺酰胺与脂族或芳族伯胺或肼反应，得到相应的硫脲。这些化合物中的某些显示出对同工酶I，II和IX的优异抑制特性，并且几种抑制剂还显示出对CA IX的抑制作用比对普遍存在的同工酶CA II的选择性。基于对在低氧肿瘤中过表达的CA同工酶的抑制作用，此类磺酰胺可能构成开发新型抗肿瘤疗法的有趣候选物。由于CA IX在

  Carbonic anhydrase inhibitors. Part 61. Quantum chemical QSAR of a group of benzenedisulfonamides

  摘要：

  The synthesis of a large group of benzenesulfonamides containing both a primary and secondary sulfonamide moiety is described. These compounds are powerful inhibitors of several isozymes of the enzyme carbonic anhydrase. Separate QSAR's are given for inhibition of three of these isozymes, using descriptors mainly derived from molecular orbital calculations by the semiempirical AM1 method. Activity was found to depend on electrostatic potential-based charges on the atoms of both sulfonamide groups, HOMO and LUMO energies, dipole moments, and lipophilicities. These results are compared with those from other studies. (C) Elsevier, Paris.

  A series of compounds incorporating both sulfonamide and sulfamide as zinc-binding groups (ZBGs) are reported as inhibitors of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1). Crystallographic studies on the complex of hCA II with the lead compound of this series, namely, 4-sulfamido-benzenesulfonamide, revealed the binding of two molecules in the enzyme active site cavity, the first one canonically coordinated to the zinc ion by means of the sulfonamide group and the second one located at the entrance of the cavity. This observation led to the design of elongated molecules incorporating these two ZBGs, separated by a linker of proper length, to allow the simultaneous binding to these different sites. The "long" inhibitors indeed showed around 10 times better enzyme inhibitory properties as compared to the shorter molecules against four physiologically relevant human (h) isoforms, hCA I, II, IX, and XII.

  Polyfluorinated carbonic anhydrase inhibitors (CAIs) show very good inhibitory properties against carbonic anhydrase (CA) and excellent in vivo antiglaucoma properties after topical administration in rabbits. Still, the pentafluorinated compounds reported previously by this group (Scozzafava et al. J. Med. Chem. 2000, 43, 4542-4551) showed high reactivity with thiol groups of cysteine, glutathione, and presumably other proteins containing such moieties, which may lead to severe ocular side effects. Here, we report an approach for obtaining fluorinated CA inhibitors without the undesired enhanced reactivity. Thus, new compounds have been obtained by attaching moieties with reduced reactivity toward aromatic substitution reactions to the molecules of aromatic/heterocyclic sulfonamides possessing derivatizable amino moieties. The employed tails of the 2,3,5,6-tetrafluorobenzoyl, 2,3,5,6-tetrafluophenylsulfonyl, and pentafluorophenylureido types induced excellent CA inhibitory properties in the new reported sulfonamides, mainly against the isozymes involved in aqueous humor secretion, CA II and CA IV, whereas affinity for CA I was lower. Several low-nanomolar CA II inhibitors were detected, which did not react with cysteine or glutathione, in contrast to the corresponding perfluorinated compounds previously reported. These derivatives also showed a potent reduction of the intraocular pressure (IOP) in hypertensive rabbits, amounting to 13-21 mmHg at 1 h postadministration (compared to 5 mmHg obtained with dorzolamide, a clinically used drug), and the decreased IOP was maintained for 4-5 h after the administration. These compounds constitute valuable candidates for obtaining topically acting antiglaucoma CA inhibitors of a new generation, with enhanced efficacy, prolonged duration of action, and reduced side effects.
